What is being made fun of is not that apples map service isn't perfect. Everybody understand that a new software system of this scale will have errors and flaws, and a lot of them.

The point is that Apple chose to replace a good and reliable service with an inferior service when it's obvious that apples own map service is at beta quality, if not worse. Apples own system was launched prematurely

Plus: forced on customers without opt-out, which is in fact hindering competition!
